Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Unknown Cook Failure

When trying to package my game for distribution, the build fails and I get an error called "PackagingResults:Error: Error Unknown Cook Failure", and I'm not sure what's causing it. My best guess is it's trying to find old references to assets that were deleted, but I wouldn't know why it's trying to do so or how to clear those references. Maybe a Fix Up Redirectors will help?

The output log was too large to attach, but I've included the automation log it's referencing.
